IF they are all Sharp displays, could that explain relatively crappy screen performance?
Even I was also convinced on the past. But when the kernel source code was released this confirmed the real display being used.
There are actually 3 types of TF displays in general which are being used by phones.
AH-IPS, LTPS and ASV
AH-IPS are somewhat the AMOLED killer(Might be the display used by HTC)
LTPS which is being used by Xperia Z/ZL are the displays which is famous for being low power
ASV on which has the advantage of having a clear wide angle display.
I assume sony did get the LTPS display for utilizing the low power feature it has. This probably the reason why every review we get says that we are having excellent battery life for a 5 incher phone with high end chipsets.
So I'm not sure about what you're saying about crappy screen performance but if you're talking about the angle washed out issue then probably this is a screen issue.
If it's the saturation of the overall screen I'd say it's a software issue
I'm sure sony could fix it. It's just a matter of setting the ARGB values of windows manager of ROM they compiled.
This must be the reason also why Docomo version has good display while others aren't. Assuming that the Docomo version is a customized OS and not the generic one probably different developers must have made/compiled the OS.
